170mm Sram Red Carbon 10sp crankset. Chain ring is mounted on the inside of the arm.
looks like it could lose 4-5mm toward the chain stay, although my heels are closer on this than any other bike I’ve had.
It’s definitely a combination of parts that aren’t ideal. I’ll keep an eye out for a 165mm single speed crankset.
It would obviously work better as a single speed, but where’s the fun in that.
